global vars across modules

[mamboknave at gmail.com]

I need to use global var across files/modules:

# file_1.py
a = 0
def funct_1() :
    a = 1	# a is global
    print(a)


# file_2.py
from file_1 import *
def main() :
	funct_1()
	a = 2	# a is local, it's not imported
	print(a)

Here above 'a' is not imported from file_1, it's local.
The only way I was able to access the global 'a' is the following:

# file_2.py
from file_1 import *
import file_1
def main() :
	funct_1()
	file_1.a = 2	# a is the global from file_1
	print(file_1.a)


Question:
How can I access to the global 'a' in file_2 without resorting to the whole name 'file_1.a' ?

Thanks!
